timers and arguments

Luke Anthony

Hi,

I'm trying to pass an object to a timer I have in my code.

I've configured the timer through the BIOS config file (statically)

...

timer0Params.arg = "&arg0";

...

and in the ISR of the timer

...

Void myTimer( UArg myArg)
{
myStruct_t *pMyPointer = (myStruct*)myArg;

...

Where can I set arg0 = the correct object to be passed in?  Should the timer be configured dynamically at run time instead?

thanks

    Yes, I would suggest constructing the timer at runtime. You can set timer arg to the address of the Timer object structure.

    Untested example:

*.c:

    Timer_Handle timer0Handle;
Timer_Struct timer0;

main() {
    Timer_Params params;

    ...
    Timer_Params_init (&params);
    params.arg = &timer0;
    params.period = <period>;
    ...
    Timer_construct (&timer0, 0, &myTimerFunc, &params, &eb);
    ...
        timer0Handle = Timer_handle (&timer0);
}

    Best,
